Correct Answer - Option 2 : 4%
Given:
Selling price of article A = Rs. 1888
Profit on article A = 18%
Selling price of article B = Rs. 1440
Loss on article B = 10%
Formula used:
Profit% or Loss% = {(Profit or Loss)/Cost Price} × 100
Calculation:
Cost price of article A is
118% = 1888
⇒ 100% = 1888 × (100/118)
⇒ 100% = Rs. 1600
Cost price of article B is
90% = 1440
⇒ 100% = 1440 × (100/90)
⇒ 100% = Rs. 1600
Total cost price = 1600 + 1600 = Rs. 3200
Total selling price = 1888 + 1440 = Rs. 3328
Profit = 3328 - 3200 = Rs. 128
Profit% = (128/3200) × 100 = 4%
∴ The overall profit is 4%.
